Coast's possession (including claims and credit balances), and all proceeds of
any of the foregoing (including proceeds of any insurance policies, proceeds of
proceeds, and claims against third parties), all products of any of the
foregoing, and all books and records related to any of the foregoing (all of the
foregoing, together with all other property in which Coast may now or in the

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
-------------------------------------------------------------------------



and that Borrower will at all times comply with all of the following 
covenants:

          3.1  CORPORATE EXISTENCE AND AUTHORITY.  Borrower, if a corporation,
is and will continue to be, duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation.  Borrower is
and will continue to be qualified and licensed to do business in all
jurisdictions in which any failure to do so would have a material adverse effect
on Borrower.  The execution, delivery and performance by Borrower of this
Agreement, and all other documents contemplated hereby (i) have been duly and
validly authorized, (ii) are enforceable against Borrower in accordance with
their terms (except as enforcement may be limited by equitable principles and by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
creditors' rights generally), and (iii) do not violate Borrower's articles or
certificate of incorporation, or Borrower's by-laws, or any law or any material
agreement or instrument which is binding upon Borrower or its property, and (iv)
do not constitute grounds for acceleration of any material indebtedness or
obligation under any material agreement or instrument which is binding upon
Borrower or its property.

          3.2  NAME; TRADE NAMES AND STYLES.  The name of Borrower set forth in
the heading to this Agreement is its correct name.  Listed on the Schedule are
all prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Coast 30 days' prior written notice before changing its name
or doing business under any other name.  Borrower has complied, and will in the
future comply, with all laws relating to the conduct of business under a
fictitious business name.

          3.3  PLACE OF BUSINESS; LOCATION OF COLLATERAL.  The address set forth
in the heading to this Agreement is Borrower's chief executive office.  In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule.  Borrower will give Coast at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.

          3.4  TITLE TO COLLATERAL; PERMITTED LIENS.  Borrower is now, and will
at all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower.  The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens.  Coast now has, and
will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Coast and the Collateral against all claims of
others.  None of the Collateral now is or will be affixed to any real property
in such a manner, or with such intent, as to become a fixture.  Borrower is not
and will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises.  Whenever any
Collateral is located upon premises in which any third party has an interest
(whether as owner, mortgagee, beneficiary under a deed of trust, lien or
otherwise), Borrower shall, whenever requested by Coast, use its best efforts to
cause such third party to execute and deliver to Coast, in form acceptable to
Coast, such waivers and subordinations as Coast shall specify, so as to ensure
that Coast's rights in the Collateral are, and will continue to be, superior to
the rights of any such third party.  Borrower will keep in full force and
effect, and will comply with all the terms of, any lease of real property where
any of the Collateral now or in the future may be located.

          3.5  MAINTENANCE OF COLLATERAL.  Borrower will maintain the Collateral
in good working condition, and Borrower will not use the Collateral for any
unlawful purpose.  Borrower will immediately advise Coast in writing of any
material loss or damage to the Collateral.

          3.6  BOOKS AND RECORDS.  Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

          3.7  FINANCIAL CONDITION, STATEMENTS AND REPORTS.  All financial
statements now or in the future delivered to Coast have been, and will be,
prepared in conformity with generally accepted accounting principles (except, in
the case of unaudited financial statements, for the absence of footnotes and
subject to normal year-end adjustments) and now and in the future will fairly
reflect the financial condition of Borrower, at the times and for the periods
therein stated.  Between the last date covered by any such statement provided to
Coast and the date hereof, there has been no material adverse change in the
financial condition or business of Borrower.  Borrower is now and will continue
to be solvent.     

          3.8  TAX RETURNS AND PAYMENTS; PENSION CONTRIBUTIONS.  Borrower has 
timely filed, and will timely file, all tax returns and reports required by 
foreign, federal, state and local law, and Borrower has 

                                       2

<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
-------------------------------------------------------------------------



timely paid, and will timely pay, all foreign, federal, state and local 
taxes, assessments, deposits and contributions now or in the future owed by 
Borrower.  Borrower may, however, defer payment of any contested taxes, 
provided that Borrower (i) in good faith contests Borrower's obligation to 
pay the taxes by appropriate proceedings promptly and diligently instituted 
and conducted, (ii) notifies Coast in writing of the commencement of, and any 
material development in, the proceedings, and (iii) posts bonds or takes any 
other steps required to keep the contested taxes from becoming a lien upon 
any of the Collateral.  As of the date hereof, Borrower is unaware of any 
claims or adjustments proposed for any of Borrower's prior tax years which 
could result in additional taxes becoming due and payable by Borrower.  
Borrower has paid, and shall continue to pay all amounts necessary to fund 
all present and future pension, profit sharing and deferred compensation 
plans in accordance with their terms, and Borrower has not and will not 
withdraw from participation in, permit partial or complete termination of, or 
permit the occurrence of any other event with respect to, any such plan which 
could result in any liability of Borrower, including any liability to the 
Pension Benefit Guaranty Corporation or its successors or any other 
governmental agency. Borrower shall, at all times, utilize the services of an 
outside payroll service providing for the automatic deposit of all payroll 
taxes payable by Borrower.  

          3.9  COMPLIANCE WITH LAW.  Borrower has complied, and will comply, in
all material respects, with all provisions of all material foreign, federal,
state and local laws and regulations relating to Borrower, including, but not
limited to, those relating to Borrower's ownership of real or personal property,
the conduct and licensing of Borrower's business, and environmental matters.

          3.10  LITIGATION.  Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted.  Borrower will
promptly inform Coast in writing of any claim, proceeding, litigation or
investigation in the future threatened or instituted by or against Borrower
involving any single claim of Fifty Thousand Dollars ($50,000.00) or more, or
involving One Hundred Thousand Dollars ($100,000.00) or more in the aggregate.

          3.11  USE OF PROCEEDS.  All proceeds of all Loans shall be used solely
for lawful business purposes.  Borrower is not purchasing or carrying any
"margin stock" (as defined in Regulation G of the Board of Governors of the
Federal Reserve System) and no part of the proceeds of any Loan will be used to
purchase or carry any "margin stock" or to extend credit to others for the
purpose of purchasing or carrying any "margin stock." 

          4.   RECEIVABLES.

          4.1  REPRESENTATIONS RELATING TO RECEIVABLES.  Borrower represents and
warrants to Coast as follows:  Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made,
represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business.

          4.2  REPRESENTATIONS RELATING TO DOCUMENTS AND LEGAL COMPLIANCE. 
Borrower represents and warrants to Coast as follows:  All statements made and
all unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be. 
All sales and other transactions underlying or giving rise to each Receivable
shall fully comply with all applicable laws and governmental rules and
regulations.  All signatures and indorsements on all documents, instruments, and
agreements relating to all Receivables are and shall be genuine, and all such
documents, instruments and agreements are and shall be legally enforceable in
accordance with their terms.

          4.3  SCHEDULES AND DOCUMENTS RELATING TO RECEIVABLES.  Borrower shall
deliver to Coast transaction reports and loan requests, schedules of
Receivables, and schedules of collections, all on Coast's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Coast's security interest and other rights in all of
Borrower's Receivables, nor shall Coast's failure to advance or lend against a
specific Receivable affect or limit Coast's security interest and other rights
therein.  Loan requests received after 10:30 AM will not be considered by Coast
until the next Business Day.  Together with each such schedule, or later if
requested by Coast, Borrower shall furnish Coast with copies (or, at Coast's

                                       3

<PAGE>

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
-------------------------------------------------------------------------



request, originals) of all contracts, orders, invoices, and other similar
documents, and all original shipping instructions, delivery receipts, bills of
lading, and other evidence of delivery, for any goods the sale or disposition of
which gave rise to such Receivables, and Borrower warrants the genuineness of
all of the foregoing.  Borrower shall also furnish to Coast an aged accounts
receivable trial balance in such form and at such intervals as Coast shall 
request.  In addition, Borrower shall deliver to Coast, upon Coast's request,
the originals of all instruments, chattel paper, security agreements, guarantees
and other documents and property evidencing or securing any Receivables, upon
receipt thereof and in the same form as received, with all necessary
indorsements, all of which shall be with recourse.  Borrower shall also provide
Coast with copies of all credit memos as and when requested by Coast.

          4.4  COLLECTION OF RECEIVABLES.  Borrower shall have the right to
collect all Receivables, unless and until an Event of Default has occurred. 
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Coast, and Borrower shall deliver all such payments and proceeds to Coast within
one Business Day after receipt by Borrower, in their original form, duly
endorsed to Coast, to be applied to the Obligations in such order as Coast shall
determine.  Coast may, in its discretion, require that all proceeds of
Collateral be deposited by Borrower into a lockbox account, or such other
"blocked account" as Coast may specify, pursuant to a blocked account agreement
in such form as Coast may specify.  Coast or its designee may, at any time with
prior notice to Borrower notify Account Debtors that Coast has been granted a
security interest in the Receivables.      

          4.5. REMITTANCE OF PROCEEDS.  All proceeds arising from the
disposition of any Collateral shall be delivered to Coast within one Business
Day after receipt by Borrower, in their original form, duly endorsed to Coast,
to be applied to the Obligations in such order as Coast shall determine. 
Borrower agrees that it will not commingle proceeds of Collateral with any of
Borrower's other funds or property, but will hold such proceeds separate and
apart from such other funds and property and in  a constructive trust for Coast.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.

          4.6  DISPUTES.  Borrower shall notify Coast promptly of all disputes
or claims relating to Receivables.  Borrower shall not forgive (completely or
partially), compromise or settle any Receivable for less than payment in full,
or agree to do any of the foregoing, except that Borrower may do so, provided
that: (i) Borrower does so in good faith, in a commercially reasonable manner,
in the ordinary course of business, and in arm's length transactions, which are
reported to Coast on the regular reports provided to Coast; (ii) no Default or
Event of Default has occurred and is continuing; and (iii) taking into account
all such discounts settlements and forgiveness, the total outstanding Loans will
not exceed the Credit Limit.  Coast may, at any time after the occurrence of an
Event of Default, settle or adjust disputes or claims directly with Account
Debtors for amounts and upon terms which Coast considers advisable in its
reasonable credit judgment and, in all cases, Coast shall credit Borrower's Loan
account with only the net amounts received by Coast in payment of any
Receivables.

          4.7  RETURNS.  Provided no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and promptly issue a credit memorandum to the Account Debtor in
the appropriate amount.  In the event any attempted return occurs after the
occurrence of any Event of Default, Borrower shall (i) hold the returned
Inventory in trust for Coast, (ii) segregate all returned Inventory from all of
Borrower's other property, (iii) conspicuously label the returned Inventory as
subject to Coast's security interest, and (iv) immediately notify Coast of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Coast's request deliver such
returned Inventory to Coast.  

          4.8  VERIFICATION.  Coast may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters relating
to the Receivables, by means of mail, telephone or otherwise, either in the name
of Borrower or Coast or such other name as Coast may choose. 

          4.9  NO LIABILITY.  Coast shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Coast be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable.  Nothing herein shall, however, relieve Coast from liability for its
own  negligence or willful misconduct.

          5.   ADDITIONAL DUTIES OF THE BORROWER.

                                       4

comply with the financial and other covenants set forth in the Schedule.

          5.2  INSURANCE.  Borrower shall, at all times insure all of the
tangible personal property Collateral and carry such other business insurance,
with insurers reasonably acceptable to Coast, in such form and amounts as Coast
may reasonably require, and Borrower shall provide evidence of such insurance to
Coast, so that Coast is satisfied that such insurance is, at all times, in full
force and effect.  All liability insurance policies of Borrower shall name Coast
as an additional insured, and all property casualty and related insurance
policies of Borrower shall name Coast as a loss payee thereon and Borrower shall
cause a lenders loss payee endorsement in form reasonably acceptable to Coast. 
Upon receipt of the proceeds of any such insurance, Coast shall apply such
proceeds in reduction of the Obligations as Coast shall determine in its sole
discretion, except that, provided no Default or Event of Default has occurred
and is continuing, Coast shall release to Borrower insurance proceeds with
respect to Equipment and Inventory totaling less than Fifty Thousand Dollars
($50,000.00), which shall be utilized by Borrower for the replacement of the
Equipment with respect to which the insurance proceeds were paid.  Coast may
require reasonable assurance that the insurance proceeds so released will be so
used.  If Borrower fails to provide or pay for any insurance, Coast may, but is
not obligated to, obtain the same at Borrower's expense.  Borrower shall
promptly deliver to Coast copies of all reports made to insurance companies.

          5.3  REPORTS.  Borrower, at its expense, shall provide Coast with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales projections, operating plans and
other financial documentation), as Coast shall from time to time reasonably
specify.

          5.4  ACCESS TO COLLATERAL, BOOKS AND RECORDS.  At reasonable times,
and on one Business Day's notice, Coast, or its agents, shall have the right to
inspect, audit and copy Borrower's books and records and the Collateral (the
"Audits").  Coast shall take reasonable steps to keep confidential all
confidential information obtained in any Audit, but Coast shall have the right
to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process.  The Audits
shall be at Borrower's expense and the charge for the Audits shall be Seven
Hundred Fifty Dollars ($750.00)  per person per day (or such higher amount as
shall represent Coast's then current standard charge for the same), plus
reasonable out of pocket expenses.  Borrower will not enter into any agreement
with any accounting firm, service bureau or third party to store Borrower's
books or records at any location other than Borrower's Address, without first
notifying Coast of the same and obtaining the written agreement from such
accounting firm, service bureau or other third party to give Coast the same
rights with respect to access to books and records and related rights as Coast
has under this Loan Agreement.    

          5.5  NEGATIVE COVENANTS.  Borrower shall not, without Coast's prior
written consent, do any of the following:  

    (i)  merge or consolidate with another corporation or entity, except in a
transaction in which (A) the shareholders of the Borrower hold at least 50% of
the common stock and all other capital stock of the surviving corporation
immediately after such merger or consolidation, and (B) the Borrower is the
surviving corporation; 

    (ii) acquire any assets, except (A) in the ordinary course of business, or

Borrower, for an aggregate purchase price not to exceed Fifty Thousand Dollars
($50,000.00) in any fiscal year; 

    (xii) make any change in Borrower's capital structure which would have a
material adverse effect on Borrower or on the prospect of repayment of the
Obligations; or 

    (xiii) dissolve or elect to dissolve.  

Transactions permitted by the foregoing provisions of this Section are only
permitted if no Default or Event of Default would occur as a result of such
transaction.  

          5.6  LITIGATION COOPERATION.  Should any third-party suit or
proceeding be instituted by or against Coast with respect to any Collateral or
relating to Borrower, Borrower shall, without expense to Coast, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Coast may deem them reasonably necessary in order to
prosecute or defend any such suit or proceeding.

          5.7  INDEMNITY.  Borrower hereby agrees to indemnify Coast and hold
Coast harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, reasonable costs and expenses
(including reasonable attorneys' fees), of every nature, character and
description, which Coast may sustain or incur based upon or arising out of any
of the Obligations, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Coast and Borrower, any actual or alleged failure of Coast
to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Coast relating to Borrower or
the Obligations (except any such amounts sustained or incurred as the result of
the  negligence or willful misconduct of Coast).  Notwithstanding any provision
in this Agreement to the contrary, the indemnity agreement set forth in this
Section shall survive any termination of this Agreement and shall for all
purposes continue in full force and effect. 

          5.8  FURTHER ASSURANCES.  Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem
reasonably necessary or useful in order to perfect and maintain Coast's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

          6.   TERM.

          6.1  MATURITY DATE.  This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the "Maturity Date"); provided that the
Maturity Date shall automatically be extended, and this Agreement shall
automatically and continuously renew, for successive additional terms of one
year each, unless one party gives written notice to the other, not less than
sixty (60) days prior to the next Maturity Date, that such party elects to
terminate this Agreement effective on the next Maturity Date.  If this Agreement
is renewed under this Section 6.1, Borrower shall pay to Coast a renewal fee

be due and payable on the effective date of renewal and thereafter shall incur
interest at a rate equal to the rate applicable to the Receivable Loans.

          6.2  EARLY TERMINATION.  This Agreement may be terminated prior to the
Maturity Date as follows:  (i) by Borrower, effective three Business Days after
written notice of termination is given to Coast; or (ii) by Coast at any time
after the occurrence of an Event of Default, without notice, effective
immediately.  If this Agreement is terminated by Borrower or by Coast under this
Section 6.2, Borrower shall pay to Coast a termination fee (the "Early
Termination Fee") in the amount shown on the Schedule.  The Early Termination
Fee shall be due and payable on the effective date of termination and thereafter
shall bear interest at a rate equal to the rate applicable to the Receivable
Loans.

          6.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any 
earlier effective date of termination, Borrower shall pay and perform in full 
all Obligations, whether evidenced by installment notes or otherwise, and 
whether or not all or any part of such Obligations are otherwise then due and 
payable. Without limiting the generality of the foregoing, if on the Maturity 
Date,  or on any earlier effective date of termination, there are any 
outstanding Letters of Credit issued by Coast or issued by another 
institution based upon an application,

guarantee, indemnity or similar agreement on the part of Coast,
then on such date Borrower shall provide to Coast cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Coast's then
standard form cash pledge agreement.  Notwithstanding any termination of this
Agreement, all of Coast's security interests in all of the Collateral and all of
the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Coast, Coast may, in its sole discretion, refuse to make any further Loans after
termination.  No termination shall in any way affect or impair any right or
remedy of Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, until all of the Obligations have been paid and performed
in full.  Upon payment and performance in full of all the Obligations and
termination of this Agreement, Coast shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Coast's security interests.

Coast may cease making any Loans hereunder during any of the above cure periods,
and thereafter if an Event of Default has occurred.  

          7.2  REMEDIES.  Upon the occurrence, and during the continuance, of
any Event of Default, Coast, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: 

          (a)  Cease making Loans or otherwise extending credit to Borrower
under this Agreement or any other document or agreement; 

          (b)  Accelerate and declare all or any part of the Obligations to be

be found, and for that purpose Borrower hereby authorizes Coast without judicial
process to enter onto any of Borrower's premises without interference to search
for, take possession of, keep, store, or remove any of the Collateral, and
remain on the premises or cause a custodian to remain on the premises in
exclusive control thereof, without charge for so long as Coast deems it
reasonably necessary in order to complete the enforcement of its rights under
this Agreement or any other agreement; provided, however, that should Coast seek
to take possession of any of the Collateral by Court process, Borrower hereby
irrevocably waives: 

                    (i)  any bond and any surety or security relating thereto
     required by any statute, court rule or otherwise as an incident to such
     possession; 

                    (ii)  any demand for possession prior to the commencement of
     any suit or action to recover possession thereof; and 

                    (iii)  any requirement that Coast retain possession of, and
     not dispose of, any such Collateral until after trial or final judgment; 

          (d)  Require Borrower to assemble any or all of the Collateral and
make it available to Coast at places designated by Coast which are reasonably
convenient to Coast and Borrower, and to remove the Collateral to such locations

          (f)  Sell, lease or otherwise dispose of any of the Collateral, in 
its condition at the time Coast obtains possession of it or after further 
manufacturing, processing or repair, at one or more public and/or private 
sales, in lots or in bulk, for cash, exchange or other property, or on 
credit, and to adjourn any such sale from time to time without notice other 
than oral announcement at the time scheduled for sale.  Coast shall have the 
right to conduct such disposition on Borrower's premises without charge, for 
such time or times as Coast deems 

                                       8

     LOAN AND SECURITY AGREEMENT                         COAST BUSINESS CREDIT
-------------------------------------------------------------------------



reasonable, or on Coast's premises, or elsewhere and the Collateral need not 
be located at the place of disposition.  Coast may directly or through any 
affiliated company purchase or lease any Collateral at any such public 
disposition, and if permissible under applicable law, at any private 
disposition.  Any sale or other disposition of Collateral shall not relieve 
Borrower of any liability Borrower may have if any Collateral is defective as 
to title or physical condition or otherwise at the time of sale; 

          (g)  Demand payment of, and collect any Receivables and General
Intangibles comprising Collateral and, in connection therewith, Borrower
irrevocably authorizes Coast to endorse or sign Borrower's name on all
collections, receipts, instruments and other documents, to take possession of
and open mail addressed to Borrower and remove therefrom payments made with
respect to any item of the Collateral or proceeds thereof, and, in Coast's sole
discretion, to grant extensions of time to pay, compromise claims and settle
Receivables and the like for less than face value; 

          (h)  Offset against any sums in any of Borrower's general, special or
other Deposit Accounts with Coast; and 

          (i)  Demand and receive possession of any of Borrower's federal and
state income tax returns and the books and records utilized in the preparation
thereof or referring thereto.  All reasonable attorneys' fees, expenses, costs,
liabilities and obligations incurred by Coast with respect to the foregoing
shall be due from the Borrower to Coast on demand. Coast may charge the same to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as is applicable to the Receivable Loans.  Without limiting any of Coast's
rights and remedies, from and after the occurrence of any Event of Default, the
interest rate applicable to the Obligations shall be increased by an additional
three percent per annum.

          7.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.  Borrower
and Coast agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable:  

          (a)  Notice of the sale is given to Borrower at least seven (7) days
prior to the sale, and, in the case of a public sale, notice of the sale is
published at least seven (7) days before the sale in a newspaper of general
circulation in the county where the sale is to be conducted; 

          (b)  Notice of the sale describes the collateral in general, non-
specific terms; 

          (c)  The sale is conducted at a place designated by Coast, with or
without the Collateral being present; 

          (d)  The sale commences at any time between 8:00 a.m. and 6:00 p.m;  

          (e)  Payment of the purchase price in cash or by cashier's check or
wire transfer is required; 

          (f)  With respect to any sale of any of the Collateral, Coast may (but
is not obligated to) direct any prospective purchaser to ascertain directly from
Borrower any and all information concerning the same.  Coast shall be free to
employ other methods of noticing and selling the Collateral, in its discretion,
if they are commercially reasonable.

          7.4  POWER OF ATTORNEY.  Upon the occurrence, and during the
continuance, of any Event of Default, without limiting Coast's other rights and
remedies, Borrower grants to Coast an irrevocable power of attorney coupled with
an interest, authorizing and permitting Coast (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Coast agrees
to exercise the following powers in a commercially reasonable manner:  

          (a)  Execute on behalf of Borrower any documents that Coast may, in
its sole discretion, deem advisable in order to perfect and maintain Coast's
security interest in the Collateral, or in order to exercise a right of Borrower
or Coast, or in order to fully consummate all the transactions contemplated
under this Agreement, and all other present and future agreements; 

          (b)  Execute on behalf of Borrower any document exercising,
transferring or assigning any option to purchase, sell or otherwise dispose of
or to lease (as lessor or lessee) any real or personal property which is part of
Coast's Collateral or in which Coast has an interest; 

          (c)  Execute on behalf of Borrower, any invoices relating to any 
Receivable, any draft against any Account Debtor and any notice to any 
Account Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim 
of mechanic's, materialman's or other lien, or 

                                       9

-------------------------------------------------------------------------



assignment or satisfaction of mechanic's, materialman's or other lien; 

          (d)  Take control in any manner of any cash or non-cash items of
payment or proceeds of Collateral; endorse the name of Borrower upon any
instruments, or documents, evidence of payment or Collateral that may come into
Coast's possession;

          (e)  Endorse all checks and other forms of remittances received by
Coast; 

          (f)  Pay, contest or settle any lien, charge, encumbrance, security
interest and adverse claim in or to any of the Collateral, or any judgment based
thereon, or otherwise take any action to terminate or discharge the same; 

          (g)  Grant extensions of time to pay, compromise claims and settle
Receivables and General Intangibles for less than face value and execute all
releases and other documents in connection therewith; 

          (h)  Pay any sums required on account of Borrower's taxes or to secure
the release of any liens therefor, or both; 

          (i)  Settle and adjust, and give releases of, any insurance claim that
relates to any of the Collateral and obtain payment therefor; 

          (j)  Instruct any third party having custody or control of any books 
or records belonging to, or relating to, Borrower to give Coast the same rights
of access and other rights with respect thereto as Coast has under this 
Agreement; and

          (k)  Take any action or pay any sum required of Borrower pursuant to
this Agreement and any other present or future agreements.  Any and all
reasonable sums paid and any and all reasonable costs, expenses, liabilities,
obligations and attorneys' fees incurred by Coast with respect to the foregoing
shall be added to and become part of the Obligations, and shall be payable on
demand.  Coast may charge the foregoing to Borrower's loan account and the
foregoing shall thereafter bear interest at the same rate applicable to the
Receivable Loans.  In no event shall Coast's rights under the foregoing power of
attorney or any of Coast's other rights under this Agreement be deemed to
indicate that Coast is in control of the business, management or properties of
Borrower.

          7.5  APPLICATION OF PROCEEDS.  All proceeds realized as the result of
any sale of the Collateral shall be applied by Coast first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by Coast
in the exercise of its rights under this Agreement, second to the interest due
upon any of the Obligations, and third to the principal of the Obligations, in
such order as Coast shall determine in its sole discretion.  Any surplus shall
be paid to Borrower or other persons legally entitled thereto; Borrower shall
remain liable to Coast for any deficiency.  If, Coast, in its sole discretion,
directly or indirectly enters into a deferred payment or other credit
transaction with any purchaser at any sale of Collateral, Coast shall have the
option, exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Coast of the cash therefor.

          7.6  REMEDIES CUMULATIVE.  In addition to the rights and remedies set
forth in this Agreement, Coast shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Coast and Borrower, and all of such rights and
remedies are cumulative and none is exclusive.  Exercise or partial exercise by
Coast of one or more of its rights or remedies shall not be deemed an election,
nor bar Coast from subsequent exercise or partial exercise of any other rights
or remedies.  The failure or delay of Coast to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid and performed.

          9.2  APPLICATION OF PAYMENTS.  All payments with respect to the
Obligations may be applied, and in Coast's sole discretion reversed and re-
applied, to the Obligations, in such order and manner as Coast shall determine
in its sole discretion.

          9.3  CHARGES TO ACCOUNTS.  Coast may, in its discretion, require that
Borrower pay monetary Obligations in cash to Coast, or charge them to Borrower's
Loan account, in which event they will bear interest at the same rate applicable
to the Loans.  Coast may also, in its discretion, charge any monetary
Obligations to Borrower's Deposit Accounts maintained with Coast.

          9.4  MONTHLY ACCOUNTINGS.  Coast shall provide Borrower monthly with
an account of advances, charges, expenses and payments made pursuant to this
Agreement.  Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Coast), unless Borrower
notifies Coast in writing to the contrary within thirty days after each account
is rendered, describing the nature of any alleged errors or omissions.

          9.5  NOTICES.  All notices to be given under this Agreement shall be
in writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, addressed to Coast or Borrower at the addresses shown in the heading
to this Agreement, or at any other address designated in writing by one party to
the other party.  Notices to Coast shall be directed to the Commercial Finance
Division, to the attention of the Division Manager or the Division Credit
Manager.  All notices shall be deemed to have been given upon delivery in the
case of notices personally delivered, or at the expiration of one Business Day
following delivery to the private delivery service, or two Business Days
following the deposit thereof in the United States mail, with postage prepaid.  

          9.6  SEVERABILITY.  Should any provision of this Agreement be held by
any court of competent jurisdiction to be void or unenforceable, such defect
shall not affect the remainder of this Agreement, which shall continue in full
force and effect.

          9.7  INTEGRATION.  This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Coast and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement.  THERE ARE
NO ORAL UNDERSTANDINGS, REPRESENTATIONS OR AGREEMENTS BETWEEN THE PARTIES WHICH
ARE NOT SET FORTH IN THIS AGREEMENT OR IN OTHER WRITTEN AGREEMENTS SIGNED BY THE
PARTIES IN CONNECTION HEREWITH.

          9.8  WAIVERS.  The failure of Coast at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Coast shall not waive or
diminish any right of Coast later to demand and receive strict compliance
therewith.  Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar.  None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Coast shall be deemed to have been waived
by any act or knowledge of Coast or its agents or employees, but only by a
specific written waiver signed by an authorized officer of Coast and delivered
to Borrower.  Borrower waives demand, protest, notice of protest and notice of
default or dishonor, notice of payment and nonpayment, release, compromise,
settlement, extension or renewal of any commercial paper, instrument, account,
General Intangible, document or guaranty at any time held by Coast on which
Borrower is or may in any way be liable, and notice of any action

taken by Coast, unless expressly required by this Agreement.  

          9.9  NO LIABILITY FOR ORDINARY NEGLIGENCE.  Neither Coast, nor any of
its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Coast, or any
of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast, but nothing herein shall relieve Coast
from liability for its own gross negligence or willful misconduct.

          9.10  AMENDMENT.  The terms and provisions of this Agreement may not
be waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Coast.

Borrower of each and every obligation under this Agreement.

          9.12  ATTORNEYS FEES, COSTS AND CHARGES.  Borrower shall reimburse
Coast for all reasonable attorneys' fees and all filing, recording, search,
title insurance, appraisal, audit, and other reasonable costs incurred by Coast,
pursuant to, or in connection with, or relating to this Agreement (whether or
not a lawsuit is filed), including, but not limited to, any reasonable
attorneys' fees and costs Coast incurs in order to do the following: prepare and
negotiate this Agreement and the documents relating to this Agreement; obtain

enforce, any of its rights; prosecute actions against, or defend actions by,

Borrower files any lawsuit against the other predicated on a breach of this
Agreement, the prevailing party in such action shall be entitled to recover its
reasonable costs and attorneys' fees, including (but not limited to) reasonable
attorneys' fees and costs incurred in the enforcement of, execution upon or
defense of any order, decree, award or judgment.  Borrower shall also pay
Coast's standard charges for returned checks and for wire transfers, in effect
from time to time.  All attorneys' fees, costs and charges to which Coast may be
entitled pursuant to this Paragraph may be charged by Coast to Borrower's loan
account and shall thereafter bear interest at the same rate as the Receivable
Loans. 

          9.13  BENEFIT OF AGREEMENT.  The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Coast; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Coast, and any prohibited
assignment shall be void.  No consent by Coast to any assignment shall release
Borrower from its liability for the Obligations.

          9.14  PUBLICITY.  Coast is hereby authorized, at its expense, to issue
appropriate press releases and to cause a tombstone to be published announcing
the consummation of this transaction and the aggregate amount thereof.

          9.15  JOINT AND SEVERAL LIABILITY.  If Borrower consists of more than
one Person, their liability shall be joint and several, and the compromise of
any claim with, or the release of, any Borrower shall not constitute a
compromise with, or a release of, any other Borrower.

          9.16  LIMITATION OF ACTIONS.  Any claim or cause of action by Borrower
against Coast, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be
done by Coast, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a
complaint within one year after the first act, occurrence or omission upon which
such claim or cause of action, or any part thereof, is based, and the service of
a summons and complaint on an officer of Coast, or on any other person
authorized to accept service on behalf of Coast, within thirty (30) days
thereafter.  Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action.  The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Coast in its sole discretion.  This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

2.  INTEREST.

    INTEREST RATE ON LOANS
    (Section 1.2):         A rate equal to the "Prime Rate" plus 2.25% per 
                           annum. Interest is calculated on the basis of a 
                           360-day year for the actual number of days elapsed.
                           The interest rate applicable to all Loans shall be 
                           adjusted monthly as of the first day of each month, 
                           and the interest to be charged for each month shall 
                           be based on the highest "Prime Rate" in effect during
                           said month, but in no event shall the rate of 
                           interest charged for any loan in any month be less
                           than 9% per annum. "Prime Rate" means the actual
                           "Reference Rate" or the substitute therefor of the 
                           Bank of America NT & SA whether or not that rate is 
                           the lowest interest rate charged by said bank. If the
                           Prime Rate, as defined, is unavailable, "Prime Rate" 
                           shall mean the highest of the prime rates published 
                           in the Wall Street Journal on the first business day 
                           of the month, as the base rate on corporate loans at 
                           large U.S. money center commercial banks.

    INTEREST RATE REDUCTION ON LOANS


                             The rate on the Loans shall be reduced to the 
                             "Prime Rate" plus 2.00% per annum in the event 
                             Borrower reports one (1) quarter of profitability. 
                             The rate on the Loans shall be further reduced to 
                             the "Prime Rate" plus 1.75% per annum in the event 
                             Borrower reports two (2) consecutive quarters of
                             profitability. In the event Borrower reports a loss
                             in any quarter following any previous reduction in
                             the rate, the rate on the Loans shall revert back 
                             to the "Prime Rate" plus 2.25% until the Maturity 
                             Date, as it may be renewed. Borrower's 10K and 10Q 
                             filings will be used to measure profitability in 
                             connection with the rate reductions permitted under
                             this Section 2 of the Schedule. Reductions or 
                             increases will become effective in the month 
                             following the month in which Coast receives the 
                             relative 10K and 10Q filings.
